Title: Vortex flowmeter
IPC: G01F1/32
Filed: 1992-03-19
Abstract: PURPOSE:To make the heat of the fluid to be measured hardly transferable to an electronic circuit for detecting Karman vortexes in a vortex. CONSTITUTION:A vortex generating body for generating Karman vortexes is provided in a duct 2 and an ultrasonic transmitter 6 and ultrasonic receiver opposed to the transmitter 6 are mounted on the side wall of the duct 2 on the downstream side of the vortex generating body. Flanges 8 and 9 are respectively provided at both ends of the duct 2 and connected to each other by means of connecting members 10 and 11 arranged above and below the duct 2 with clearances C between the members 10 and 11 and duct 2. Then an electronic circuit for detecting the generation of a Karman vortex is attached to the top of the member 10 while the circuit is connected to the transmitter 6 and receiver. When such a constitution is used, the heat of the duct 2 is hardly transferred to the member 10 due to the clearance C between the duct 2 and member 10. Therefore, even the flow rate of a high-temperature fluid can be measured, since the electric circuit hardly receive influences from the heat of the fluid flowing through the duct 2. In addition, the deterioration of the electronic circuit caused by the heat can also be prevented.
